The best way to create that type of axes is to use the semilogy function. Alternatively, you can set the ‘YScale’ property on the axes:
set(gca, 'YScale', 'log')
***Update from Mathworks Support Team - September 2023***
As of R2023b, you can also use the 'yscale ' function. Answer from Walter Roberson on mathworks.com

Log plots in MATLAB
If you specify y as a matrix, the columns of y are plotted against the values 1:size(y,1). For example, define y as a 5-by-3 matrix and pass it to the loglog function.

xscale - Set or query x-axis scale (linear or logarithmic) - MATLAB
This code calls the nexttile function to create a tiled chart layout with one axes object. The second call to nexttile creates and returns the second axes object. x = 1:10000; y = log10(x); nexttile; plot(x,y) grid on title("Linear Scale") ax2 = nexttile; plot(x,y) grid on title("Log Scale")

Yes, it is possible. Use the loglog command.
The example from the Mathworks website:
x = logspace(-1,2); % generate a sequence of points equally spaced logarithmically
loglog(x,exp(x),'-s')
grid on
If you do not want both axes to be log scale, use semilogx or semilogy.

Log Plot Matlab | Examples to Use Log and semilogx in Matlab
March 24, 2023 - It will plot the logarithmic values in the x-axis ranging from 10^0 to 10^4. Log plots are used in the field of economics, to estimate the numerical parameters and in the field of machine learning to transform the columns if they are not normally distributed. So, depending on the requirements we can use loglog and semilogx in Matlab. This is a guide to Log Plot Matlab. Here we discuss the introduction and working with Log Plot Matlab along with the examples and outputs.
